Hello I'm trying to put together a Programmable filter that will add arrays of deformed and undeformed coordinates and undeformed angles to my PointData in 4.0.1
>From all the examples online, I think either of these examples should work but >neither does. Any hints First, I am copying arrays in the PF, so I should be able to manipulate either input or output, but neither works It is also a composite (Exodus dataset) First version - error is can't find output.Points import math def process_block(block): displ=block.PointData['DISPL'] # Coords of Points are locked into individual Point structures # Assume Displacements applied (Points are deformed) numPts=output.GetNumberOfPoints() # for i in range(numPts): # #x_coords[i], y_coords[i], z_coords[i] = output.GetPoint(i) x_coords=output.Points[:,0] y_coords=output.Points[:,1] z_coords=output.Points[:,2] x_undef=x_coords-displ[:,0] y_undef=y_coords-displ[:,1] z_undef=z_coords-displ[:,2] # Undeformed scalar Coordinates block.PointData.append(x_undef,"X_undef") block.PointData.append(y_undef,"Y_undef") block.PointData.append(z_undef,"Z_undef") # Deformed scalar Coordinates block.PointData.append(x_coords,"X_def") block.PointData.append(y_coords,"Y_def") block.PointData.append(z_coords,"Z_def") # Calc angles (no atan2 in vtk) Angles_undef=math.atan2(z_undef,x_undef) block.PointData.append(Angles_undef,"Angle_undef") for block in output: process_block(block) For second version I comment out x_coords=output.Points[;0] and use # for i in range(numPts): # #x_coords[i], y_coords[i], z_coords[i] = output.GetPoint(i) This error is can't find output.GetPoint Both of these are used in examples online of Programmable Filter, so what am I missing? I have substituted input for output above and no change. Also, output.GetNumberOfPoints works, so why doesn't output.GetPoints work? Also, I don't understand what object I should examine to find all the member functions within Input and Output within the Programmable Filter Thanks _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Follow this link to subscribe/unsubscribe: http://www.paraview.org/mailman/listinfo/paraview
